图片放大不失真软件 S-Spline V2
Published on 2006年 六月 13日, 13:15
我们经常会遇到这样的情况：把一张小尺寸的图片放大之后于本清晰的局部细节会出现很多马赛克一样的单色块。这是因为位图（以后会对该概念进行详细说明）放大过程中软件对其新建象素点进行着色的缘故。图片格式选用的压缩算法和软件放大采用的算法（例如最邻近插值,近邻取样法,双线性内插值,三次卷积法线性差值等等。可以再不明显(但是也有)降低图片质量的前提下将分辨率提升一倍(当然也可以更高,不过质量就会严重下降).该算法的核心是在原来两个象素间插入第三个象素,并使其颜色等于位于其周围象素的平均值）决定了放大之后图片的质量。
S-Spline软件是PhotoZoom Professional 的前身。虽然功能较少但是放大功能一点也不含糊。它采用了较为优秀的插值算法，这样可以获得较高的图片质量。

好玩
另外我终于学会图文混排了～～hoho，再也不用把图片稳稳当当的排在中央了。
那就赶紧拥抱他吧，文中有下载。 :-p :-p :-p
哇塞……找这类软件很久了……
你去GG看看PhotoZoom Professional有没有破解版吧或者SN。那个是最新版本，但是貌似也没有什么提高，只是加了亮度色彩对比度等等调节。是不是改进了算法我还没来得及看。 :''
